GASGLENE CUT OFF FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed April 4, 1914. Serial No. 829,717.

To all whom it may concern:

Be it known that l. STEWART SHAFER, a citizen of the United States, residing at Idaville, in the county of \Vhite and State of Indiana, hare invented certain new and useful Improvements in Gasolene Cut-Oil's for Automobiles, of which the following is a. specification, reference being had to the accompanying drawings,

This invention relates to a gasolene cutoil for automobiles.

The object of the invention is to provide an article of this character which mayreadily be applied to the ,qasolene pipe of an automobile at any part between the tank and the carhureter, the adoption of the device not requiring any change whatever in the structural arrangement of the automobile, and which in operation will be positive in preventing the use of the automobile without the owners knowledge and consent.

'With the above and other objects in view, as will appear as the nature ofthe invention is better understood, the same consists, generally stated, in a gasolene cut-oil for automobiles, comprising a cylinder, which may be of any preferred contour in cross section, and which is designed "o be scored to the gasolene supply pipe at my poiz a be tween the tank and the carhnreter. This cylinder houses a plunger which, in its lower position, positively cuts oil passage through the gasolene supply pipe, *imbined with the plunger is a novel mechs iism for holding the same elevated while pile machine is in use, the means comprising a bolt rigid with the plunger and having pivotally connected with its upper end, as by a rule joined, a latch that is designed to be brought into interlocked relation with a keeper depending from the cap or closure of the top of the cylinder. The latch is held in normally vertical position by means of leaf springs secured on opposite sides oi? the bolt and 'ertically embracing the latch, the latter being designed to be turned upon its pivot by a key of a construction that will render it difficult to imitate or reproduce.

A. further feature of the invention resides in the means for preventing access to the in terior for the purpose of unseating the plungcr or valve, the same consisting of a screw cap threaded on the upper end of the cylinder and having two positively alined screws for securing it in position, one of the screws being concealed within the cylinder, and re- Figure 1 1s a' view in vertical. section through a gasolene cut oil formed in accordance with my invention; Fig. 2 is a similar view taken at right angles to Fig.

1; Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 1.

The cylinder 1 may he made of any suitable material,'such as heavy sheet metal, and may be either circular or rectangular in cross section, preferably the former. Adjacent to the lower ends of the cylinder arid on opposite sides thereof enter the'two sections 2 and 3 of the gasolene supply pipe, one branch leading to the tank and the other to the carbureter. Passage between these pipe sections is controlled by a plunger 4 that fits snugly within the cylinder and carries an upstanding bolt 5, the upper end of which has pivotally connected with it at 6 a latch 7. The upper end of the latch terminates in an arm or catch 8, and at a point intermediate of the length of the latch and projecting in an opposite direction to the catch 8 is a pin 9. The latch is held in vertical yielding position by two leaf springs 10 secured on opposite sides of the bolt, and haying their upper ends crotched partly to embrace the-latch, so that while the'latter will be free to swing upon the pivot 6 it will normally be maintained in a vertical position.

exterior of the upper end of the cylinder is threaded and is engaged by a cap 13. from which depends a keeper ll'that is designed to coact with the catch 8 to hold the plunger in raised position and thus permit free passage of gasolene through "the pipe sections 2 and In addition to the threaded connection between the cap and the cylinder, the former is additionally held in place hy two screws 13 and 14, the screw 13 being removable from the exterior of the can, while the screw 14 is only removable from the interior of the cylinder, and is acoomplished by first 'removing the screw 13 and then inserting n eoeoialiy constructed :sCioW driver to engage Wiih the screw 14, B this arrangement, ii double inciting of the cap to the cyiinder is secured, and no coats kothe lafler'is practicsilly preciuded.

Projecting inward from one hide of the oylinder, and rigid therewith is key guide having an eye 36 to Iepeive iiie'siem 17' of a key a slot 1.8 to rebeive the ward .19 of the key, the latter being pro ided with an all through orifice 20 designed to ass over the pin 9, the guide being arranger to register with a key-.lioie-in the side of" the cylinderi From the foregoing it will be seen that when the key is inserbed through the key hole and key guide and the orifice 20 brought into engagement with the pin 9, that upon the key being turned, the latch 7 will be moved to one side against the resistance of one of the springs 10, and during this movoment the phinger will be raised. As. soon as the catch Spasses over the keeper 12, fiurther turning of the key is rendered nxineces sary, and the gasoiene wil now freely pass through the pipe sections :24 and 3. When the owner leaves the machine the key is turned in the reverse direction, thereby mov- Leg the latch out. of engagement with the keeper and {oennitting the plunger to resume its normal position, that is resting upon the bottom of the cylinder, thereby cutting ofi' the passage of the gnsolene. When ibis is aecompiished the owner removes the key, and may feel reasonably sure that his machine will not be imlawfuily used.

From the foregoing description, it will be seen that although the improvements herein described are simple in character, they will be thoroughly eflicient for the purpose designed and coaot in the presentation of a durable and highly advantageous form of gasolene out-off.

Having thus described my invention, what I claim is:

l. A gasolene out off for automobiles comprising a casing provided at its lower end with oppositely disposed pipes, a plunger arranged in the casing and operating normally to close through the pi me, a bolt carried by Elbe upper end of the p unger, a. spring pressed latch fpivotally conneeied with the upper end 0 the bolt and carrying at its upper iermn'ial an outstanding catch and at an intermediate point Pan ouistanding pin, a on) secured to the casing, and a keeper depending from the cap and arranged to be engaged l2 the catch.

2 A gasolone out o, for automobiles comprising a casing provided at its lower end with oppositely extending pi es, a plunger arranged in the casing and operating normally is out off passage through the pipes, a bolt rigid with the upper side of the plunger, a latch pivotaliy connected with the upper end of ilie'bolt and provided at its upper end with an outstanding catch, and intermediate of its ends with an outstanding pin, sprig-gs secured to opposite sides of the bolt and engaging the latch b0 hold it normally in a vertical position, a cap se cured to the upper end of the casing, a keeper depending from the cap and arranged to be engaged by the catch, and -a key having an orificed Ward to engage Fhe pin whereby to raise the plunger and tO HIlpart lateral mo ement to the latch to permit the catch to be engaged with the keeper.

3. A gasolene cut of) for automobiles comprising a casing provided in its Lower portion with oppositely d sposed pipes, a

plunger arranged in the casing and operetfi ing normally to out oii' passnge through the pipes, a bolt rigid with the plunger, 2. pivoted spring pressed latch carried by the upper end of the bolt and provided with an outstanding catch and with a pin, a cap closing the upper end of the casing, a keeper depending froiimhe cap, a key guide projecting through the side of the casing and. having its eye disposed opposite the pin and a key having an orificed ward to engage.

with the pin to raise the plunger.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
